by top dressing, did not have a positive effect on plant growth. Surface application
of this fertilizer negatively affected root development.


The introduction of superphosphate and complex fertilizer positively affected
the growth of Aleppo Pine. Better result was achieved by superphosphate.
Very good lignification of plants was determined by treatment with superphosphate
in both investigated species and a positive effect of phosphorous on development
or root system.


Additional treatment wich "Osmocote Mini"ferlizer had a stronger effect
on plant growth than "Osmocote Sierrablen".


The applied fertilization had an effect on increased concentrations of relevant
nutritional elements in the substrate and plants. Better developed plants
of Stone Pine accumulated significantly more nutriens than Aleppo Pine
plants. The use of mineral fertilizer had a strong effect on absorption of corresponding
nutriens in both investigated species.


With a dose of 1.5 kg/m3 "Osmocote Mini" high quality Stone Pine seedlings
were cultivated, while in the case of Allepo Pine the dose should be
increased.


Key words: "Osmocote Mini", "Osmocote Sierrablen", superphosphate,
NPK fertlizer 7:14:21, Pinus halepensis, Pinus pinea, growth, seedling
quality.
